comrmvsarme GEAR.

Application filed February 8, 1924. Serial No. 691,879.

To all whom it may concern:

Be it knownthat I, EDWIN J. GOULD, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Compensating Gear, of which the following is a specification.

My invention is an improved compensating gear.

The object of my invention is tel-provide a gear which is highly efficient in operation, simple in construction and inexpensive to manufacture.

This invention relates to the type of compensating gear in which the driving element is linked to the driven elements by means of straps which encircle. eccentrics on said driven elements, these straps being pivoted together at one end and linked at the other.

In the annexed drawing in which my invention is illustrated:

Figure 1 is. a side View of my gear.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is a side view of my gear with the cap removed. I

Figure 4 is a plan view of my gear.

Figure 5 is a plan view of a modified K form.

Figure 6 is a transverse sectional view of the link joining the eccentric straps.

Referring more particularly to the drawing, my gear comprises a cylindrical driving element 1, the open end of which is closed by the cover 2. The casing 1 is r0- tated from any suitable source of power (not shown).

The driven elements 33 consist of two aligned shafts which may be the rear axles of a motor vehicle. These shafts, are formed with journals 44 which rotate in bearings 5-5 in the casing 1 and cover 2. Eccentrics 66 are formed on the shafts, and.

straps 77 surround these eccentrics. A block 8 is positioned between the straps 77 and an elongated slot 9 is formed therein into which the ends of the shafts 3-3 extend. A pin 10 extends through the straps 77 and lock 8 and projects through slots 11 and 12 in the cover 2 and bottom of casing 1 respectively. The purpose of this pin and slots will be further described. The block 8 is formed with a pin 13 upon which a link 14 is journaled. Each of the straps 7 are formed with a pin 15 which project through slots 16-16 in the link 14.

If the shafts 3 rotate at a different speed from the casing 1, a transverse motion is imparted to the straps 77 and block 8 by theeccentrics 6, causing the pin 10 to reciprocate in the slots 11 and 12 and the block 8 is permitted to reciprocate because of the slot 9. If the shafts 3 rotate at different relative speeds the link 14 will tilt about the pin 13, as will be readily understood.

Slots 1.7 and 18 are formed in the casing 1 to permit the transverse motion of the straps encircling said eccentrics, a block between sald straps, means to pm said block and straps together, and a link pivoted in said block and pivotally secured to said straps. g

2. A compensating gear comprising a driving casing, a plurality of driven elements, eccentrics on said driven elements, straps encircling said eccentrics, a block between said straps, said casing having slots formed therein, a pin extending through said slots, and through one end of said straps and block, and a link pivoted to the other end of said block and pivotally secured to the straps.

3. A compensating driving casing, a pair 0 naled in said casing, eccentrics on said shafts, straps encircllng said eccentrics, a blockbetween said straps, said block hav ing a slot therein into which said shafts exsaid block and straps, and means to link fgear comprising a drlven shafts ]0111- j the other end of said block with the straps. a pin extending through one end of said 4. A compensating fgear comprising a block and straps, said casing having slots driving casing, a pair 0 driven shafts jourformed therein into which said pin extends, 10 naled in said casing, eccentrics on said a link pivoted to said block, and pivotally 6 shafts, straps encircling said eccentrics, a secured to said straps.

block between said stra s, said block havin In testimony whereof I afiix my signature. a slot therein into whic said shafts exten EDWIN J. GOTTLD.
